The technical scheme includes that the headless rivet positioning device comprises a riveter, riveting dies and three jaws evenly distributed and fixed onto a shell of the riveter by 120-degree angles, and the overhanging of the two ends of the headless rivet is effectively controlled by means of matching the upper riveting die and the lower riveting die with the three jaws.
Description
Technical field
The present invention relates to a kind of positioner, particularly relate to a kind of straight-neck rivet positioner.Also relate to the method for utilizing this straight-neck rivet positioner control straight-neck rivet two ends overhang.
Background technology
In aircraft manufacturing, the interference engagement that straight-neck rivet can be realized ideal, joint is long fatigue life.But during slug riveting,, can only accomplish by the automatic drill riveter at present owing to will accurately control the two ends overhang.But the automatic drill riveter belongs to large-scale expensive device, and use cost is very high, and much aviation enterprise does not have too many automatic drill riveter, causes the use of straight-neck rivet to be restricted.Manual rivet is easy to use, but no matter present hammer riveting still is the overhang at all uncontrollable straight-neck rivet of hand-held electromagnetic rivetter two ends.Therefore, the manual rivet of realization straight-neck rivet is significant to the extensive use of straight-neck rivet.
Summary of the invention
In order to overcome the deficiency of the uncontrollable straight-neck rivet of existing hand-held electromagnetic rivetter two ends overhang, the present invention provides a kind of straight-neck rivet positioner.This device comprises riveting gun, riveting mould and pawl, and three pawls are with the even branch in 120 degree angles and be fixed on the riveting gun shell, through cooperating of upper and lower riveting mould and three pawls, can control the overhang at straight-neck rivet two ends well.
The present invention also provides the method for utilizing this straight-neck rivet positioner control straight-neck rivet two ends overhang.
The technical solution adopted for the present invention to solve the technical problems is: a kind of straight-neck rivet positioner is put, and is characterized in comprising riveting gun, riveting mould and pawl.The riveting mould comprises lower rivet model 3 and upper rivet model 12, and lower rivet model 3 is installed on the secondary riveting gun 19, and upper rivet model 12 is installed on the main riveting gun 20.Pawl comprises palmula 6 and pawl arm 7, and palmula 6 is cylindrical, and an end is a tack; The other end is the screwed end of thread, and the end of thread is threaded with screwed hole on the pawl arm 7, and pawl arm 7 is the structures of falling L; Long end has and the perpendicular plane of axle 1 axis; There is a screwed hole at the center on plane, and short end has and the perpendicular concave station hole of axle 1 axis, and the boss 17 on the pawl arm 7 snaps into 18 li of the grooves of riveting gun shell; Soket head cap screw passes the concave station hole and riveting gun shell 9 is connected, and three pawls are with the even branch in 120 degree angles and be fixed on the riveting gun shell 9.
A kind of method of utilizing above-mentioned straight-neck rivet positioner control straight-neck rivet two ends overhang is characterized in may further comprise the steps:
Riveted joint beginning, at first for given by riveting parts 5 and straight-neck rivet 4, according to formula
L
